Sybase Central can poll at specified intervals to check the state (started or stopped) of each service, and update the icons to display the current state. By default, polling is off. If you leave it off, you must click Refresh Folder to see changes to the state.
From the Context dropdown list, choose the SQL Anywhere 10 plug-in.
In the right pane, click the Services tab.
Select the service and then from the File menu, choose Properties.
Click the Polling tab.
Select Enable Polling.
Set the polling frequency.
The frequency applies to all services, not just the one selected. The value you set in this window remains in effect for subsequent sessions until you change it.
